I too totally forgot about the knights move rule. Without the rule I thought the puzzle was at medium difficulty.

I used the Knights Move exactly once to solve the last 3 x-Wings. Forgot completely they exist
Reply: That's really interesting. What difficulty would you rate the puzzle without the anti-knight rule?
I rated it 3*, cause i had some Points where i was completly stuck for several Minutes. Im surprised i got to the end without remembering the rule

Updated rules to specify that not all X's and V's are given. Negative rule is not in effect for XV rule.

asp1310, sorry for the confusion. No, not all x's or v's are given. I'll update the rules to reflect this.

I’m guessing the negative rule is in effect for Xs and Vs, since it doesn’t say not all Xs or Vs are given, whereas it does say that for Kropki dot rule?
